The hashCode() Method of DateFormat class is used to return the hash code value of this DateFormat object. The hash code is of integer type.
Syntax:
public int hashCode()
Parameters: The method does not take any parameters.
Return Value: The method returns the hash code value of this DateFormat object and is of integer type.
Below programs illustrate the working of hashCode() Method of DateFormat:
Example 1:
// Java to illustrate hashCode() method  import java.text.*;import java.util.*;  public class DateFormat_Demo {    public static void main(String[] args)    {        // Initializing DateFormat        DateFormat DFormat            = DateFormat.getDateTimeInstance();          // Displaying the formats        Date date = new Date();        String str_Date1 = DFormat.format(date);        System.out.println("The Original: "                           + (str_Date1));          // Displaying the hash code        System.out.println("The hash code: "                           + DFormat.hashCode());    }} |
Output:
The Original: Mar 27, 2019 10:20:51 AM The hash code: 2034585966
Example 2:
// Java to illustrate hashCode() method  import java.text.*;import java.util.*;  public class DateFormat_Demo {    public static void main(String[] args)    {        // Initializing DateFormat        DateFormat DFormat            = new SimpleDateFormat("MM/dd/yyyy");          // Displaying the formats        Date date = new Date();        String str_Date1 = DFormat.format(date);        System.out.println("The Original: "                           + (str_Date1));          // Displaying the hash code        System.out.println("The hash code: "                           + DFormat.hashCode());    }} |
Output:
The Original: 03/27/2019 The hash code: 2087096576
